The O-ring of DMS SEALS is often used in hydraulic and pneumatic transmission systems and has wide applications. It can be used for both static and reciprocating seals. Moreover, it can also be used in rotary sealing systems. The O-ring can be installed in a groove with a rectangular cross section on the outer or inner circle, achieving a good sealing effect. It has many advantages compared with other types of sealing rings. Its compact structure makes it easy to assemble and disassemble. Moreover, its dynamic frictional resistance is relatively small, and a single piece of O-ring can achieve sealing performance in both directions.
DMS SEALS’ s bonded seal is ideal for being applied to threaded pipe fittings and plug sealing in Metric, British and BSP systems. The seal has no special requirements for the positioning and processing techniques of the seal groove, so it is an ideal accessory for fast and automatic installation that we highly recommend. The operating temperature range is -30°C ~ 100°C, and the working pressure is less than 39.2 MPa. It is commonly used in a hydraulic oil medium.
Scraper seals are also known as wiper seals. The scraper sealof DMS SEALS can effectively prevent various forms of contamination that cause a hydraulic system failure. It can be mounted on the outside of the piston rod seal of the hydraulic cylinder to protect the hydraulic cylinder from dirt, dust and moisture. It can well protect the hydraulic cylinder from environmental pollution and effectively prevent damage to the hydraulic cylinder parts, causing the system to malfunction. DMS offers a wide range of wiper seals for different hydraulic systems with different characteristics, specifications and combinations.
Influence of flange form: Different flange forms require different gaskets. Smooth-faced flanges are generally only used for low pressure, with soft thin gaskets; under high pressure, if the strength of the flange is sufficient, smooth-faced flanges can also be used, but thick soft gaskets should be used, or inner belt reinforcement should be used. Wound gasket for ring or reinforcement ring. In this case, metal gaskets are also not suitable, because the required pressing force is too large, resulting in large deformation of the bolts, making the flange difficult to seal. If a metal gasket is to be used, the smooth surface should be reduced to reduce the contact area with the gasket. In this way, under the condition of the same bolt tension, the compressive stress of the reduced narrow smooth surface will increase.
Although construction machinery looks extremely complex, the common characteristics that can be summarized are: Usually work outdoors. The work site often changes, and some can move by themselves. The working environment is usually dusty or stained. Nowadays, construction machinery generally adopts hydraulic transmission, because hydraulic transmission has the following obvious advantages compared with mechanical transmission: The power-to-volume ratio is large and the location arrangement is easy. It can realize stepless speed change. It is easy to realize overload protection. Less shock, vibration and noise.
